Shibuki (飛沫; Literally meaning "Splash") is one of the swords of the Seven Swordsmen of the Mist, wielded by Jinpachi Munashi. The blade utilises various explosive tags, contained within a substantial scroll, in order to incorporate explosions into the user's own swordsmanship, earning it the title of "blastsword" (爆刀, bakutō). The sword itself features two distinct sides, with a narrow cutting edge located down the entirety of one length and a wide platform section on the other. The aforementioned scroll unrolls along this latter side, sliding downwards and resting atop its surface to form an individual segment comprised from numerous explosive tags, which separates from the remainder upon detonation. Only once the desired opponent comes into contact with the platform, do the explosive tags finally ignite and then detach, providing a small opportunity for the user to escape the devastating blast radius, while simultaneously compensating for any resultant recoil. The sword is seemingly able to reload another segment of tags onto the platform, automatically after each strike.

The sword is first seen when a reincarnatedMangetsu Hōzuki summons it from a scroll, where it is then returned to its respective wielder, Jinpachi, and last seen when Jinpachi is sealed.
